Produce wheel events in a captured tab or window. 2. Read/write the zoom level of a captured tab.

Goals for experimentation Reason this experiment is being extended The status in the W3C WebRTC WG is that we have consensus on supporting the use case of forwarding zoom and wheel events from the local user to the captured tab. The API currently under trial supports this use case, but the WG does not want support use cases with non-local control (eg, co-presenting), which the current API does support. See https://www.w3.org/2024/05/21-webrtc-minutes.html#t01 We want to experiment with an alternative API shape to prevent non-local use cases, and with additional restrictions on the existing API shape. These changes will be discussed in upcoming WG meetings. Reason this experiment is being extended The experiment was shifted from the original m122-m127 to m124-m129. See https://groups.google.com/a/chromium.org/g/blink-dev/c/7MbIEBdHMck for details. Ongoing technical constraints Debuggability Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?
